Abstract

PROCEDIMIENTO DE INSTALACION DE UN MANGUITO MULTIMETALICO OBTURABLE PARA LA REPARACION DE UN TUBO DEGRADADO. EL MANGUITO (10) INCLUYE UN MIEMBRO INTERIOR (12) CON PROPIEDADES MECANICAS EQUIVALENTES A LAS DEL TUBO DEGRADADO Y UN MIEMBRO EXTERIOR (14) ADHERIDO METALURGICAMENTE AL MIEMBRO INTERIOR Y RESISTENTE AL ATAQUE QUIMICO INTERGRANULAR CAUSTICO CAUSANTE DE LA DEGRADACION DEL TUBO. EL MANGUITO TIENE UNA PORCION EXPANDIDA EN UN EXTREMO (17) PARA SITUARSE EN EL TUBO DENTRO DE LA PLACA DE TUBO Y UNA MULTIPLICIDAD DE RANURAS EN EL OTRO EXTREMO DEL MANGUITO.INSTALLATION PROCEDURE OF A SEALABLE MULTIMETALIC SLEEVE FOR THE REPAIR OF A DEGRADED TUBE. THE SLEEVE (10) INCLUDES AN INTERIOR MEMBER (12) WITH MECHANICAL PROPERTIES EQUIVALENT TO THOSE OF THE DEGRADED TUBE AND AN EXTERNAL MEMBER (14) METALLURGICALLY ADHERED TO THE INTERIOR MEMBER AND RESISTANT TO THE CHEMICAL ATTACK OF THE INTERGRANULAR TUBE CAUSTICATION. THE SLEEVE HAS A PORTION EXPANDED AT ONE END (17) TO BE LOCATED IN THE TUBE INSIDE THE TUBE PLATE AND A MULTIPLICITY OF SLOTS AT THE OTHER END OF THE SLEEVE.
